This package contains bps configuration files for running cp_pipe and eo_pipe pielines to do bias stability analyses on LSSTCam for several different ISR configurations. These include three different overscan correction methods:

1. Parallel + serial median-per-row
2. Serial median-per-row only
3. Serial mean only

Combined bias and dark frames are generated in each case so that consistent ISR configurations are used at each step.

Copy scripts/setup_base.sh to a standard location and edit the line

package_dir=/sdf/home/j/jchiang/dev

to point to the directory where the eo_pipe and bias_stability packages are installed, then copy scripts/setup.sh to a working directory and edit the line

source /sdf/home/j/jchiang/dev/bias_stability/scripts/setup_base.sh ${shared_stack_dir}

to point at the location where you've installed setup_base.sh.

All of the site- and run-dependent configurations in the bps yaml files are set via environment variables in setup.sh, so these should be set accordingly for the runtime environment used by the bps submissions.

We'll use B-protocol run 13550 to generate the combined bias and dark frames. Here's an excerpt from the setup.sh file with the relevant environment variables set:

version=`eups list lsst_distrib -s | sed 's/\s\+/\n/g' | grep [dw]_[0-9]*_[0-9]*`
export WEEKLY=${version}
export BUTLER_CONFIG=/repo/ir2
export BIAS_STABILITY_RUN=13555
export CALIB_RUN=13550
export PAYLOAD_MODIFIER=""
export SUBSELECTION=""
export BIAS_STABILITY_INCOLLECTION=u/${USER}/dark${PAYLOAD_MODIFIER}_${CALIB_RUN}_${WEEKLY}
export INSTRUMENT_CLASS_NAME=LsstCam
export INSTRUMENT_CLASS=lsst.obs.lsst.${INSTRUMENT_CLASS_NAME}
export INSTRUMENT_NAME=LSSTCam

After sourcing the updated setup.sh file, one can either copy or symlink the bps files to the local working directory, e.g.,

$ ln -s $BAIS_STABILITY_DIR/bps/bps* .

To generate the bias stability results for the parallel+serial overscan configurtion, run the following three pipelines in succession:

$ bps submit bps_cpBias_P+S.yaml
$ bps submit bps_cpDark_P+S.yaml
$ bps submit bps_eoBiasStability_P+S.yaml

For the serial_median and serial_mean cases, the corresponding bps yaml files would be run in the same fashion.
